This patent describes an apparatus for detecting radioactive particles in garments. It comprises a conveyor assembly for receiving, moving and discharging garments; and a radiation detector assembly including first and second radiation detector means, each of which includes a face that is primarily sensitive to beta radiation throughout its entire area, a shield means for shielding the first detector means from ambient radiation, and a height adjustable mounting means for mounting the first radiation detector means and the shield means over the conveyor assembly and for adjusting the distance between the detector means and the top side of the garments moved by the conveyor assembly while maintaining the shield means in the same shielding orientation relative to the detector means. The second radiation detector means being disposed under the conveyor assembly so that the first radiation detector means detects beta radiation emitted substantially from the top side of the garments while the second radiation detector means beta radiation emitted substantially from the bottom side of the garments.
